Yesterday, Sarah spent 35 and 1 over 2 minutes studying for a test. Emma spent 1 over 1 over 2
times that amount studying for a different test. How many minutes did Emma spend studying?
53 and 1 over 4 minutes
93 and 1 over 2 minutes
71 minutes
49 and 1 over 2 minutes
73 and 1 over 4 minutes
To find out how many minutes Emma spent studying, we need to multiply Sarah's study time by 1 and 1/2.
Emma's study time = (35 and 1/2 minutes) * (1 and 1/2)
First, let's convert the mixed numbers to improper fractions:
35 and 1/2 = (2 * 35) + 1/2 = 70 + 1/2 = 71/2
1 and 1/2 = (2 * 1) + 1/2 = 2 + 1/2 = 3/2
Multiply the fractions:
(71/2) * (3/2) = (71 * 3) / (2 * 2) = 213/4
Now, convert the improper fraction back to a mixed number:
213/4 = 53 and 1/4
Therefore, Emma spent 53 and 1/4 minutes studying.
A middle school band as 2 over 9
as many band members as the high school band. The high school band has 502 members. About how many members are in the middle school band?
645
390
112
45
To find the number of members in the middle school band, we need to multiply the number of members in the high school band by 2/9.
Number of members in the middle school band = (number of members in high school band) * (2/9)
Plugging in the given values:
Number of members in the middle school band = 502 * (2/9)
First, let's simplify the fraction:
2/9 = (2 * 1) / (3 * 3) = 2/18
Now, multiply the fractions:
502 * (2/18) = 1004/18
Now, divide the numerator by the denominator:
1004/18 = 56
Therefore, there are about 56 members in the middle school band.
sorry but the answers are
645
390
112
45
Apologies for the incorrect calculation. Let's recalculate it correctly:
To find the number of members in the middle school band, we need to multiply the number of members in the high school band by 2/9.
Number of members in the middle school band = (number of members in high school band) * (2/9)
Plugging in the given value:
Number of members in the middle school band = 502 * (2/9)
Now, let's perform the calculation accurately:
Number of members in the middle school band = (502 * 2) / 9
Number of members in the middle school band = 1004 / 9
Dividing 1004 by 9, we get:
Number of members in the middle school band ≈ 111.55555555555556
Therefore, there are about 112 members in the middle school band.
How much cake will each member of the team get if 6 members share 34 of a cake equally
1 over 6
1 over 8
1 over 3
1 over 4
To find out how much cake each member of the team will get, we need to divide the total amount of cake by the number of members sharing it.
Amount of cake per member = Total amount of cake / Number of members
Plugging in the given values:
Amount of cake per member = 34 / 6
Dividing 34 by 6, we get:
Amount of cake per member ≈ 5.666666666666667
Therefore, each member of the team will get about 5 and 2/3 (or 1/6) of a cake.
Twenty-four packets of sheet music are in a folder. If the chorus students decide to share 3 over 8
of the packets, how many did they share
9 packets
8 packets
18 packets
12 packets
To find out how many packets of sheet music the chorus students shared, we need to multiply the total number of packets by 3/8.
Number of packets shared by chorus students = Total number of packets * (3/8)
Plugging in the given values:
Number of packets shared by chorus students = 24 * (3/8)
Now, let's perform the calculation:
Number of packets shared by chorus students = (24 * 3) / 8
Number of packets shared by chorus students = 72 / 8
Number of packets shared by chorus students = 9
Therefore, the chorus students shared 9 packets of sheet music.
