I'll be glad to check your answers.
I'm not sure how to this
14. Multiply.
4/5 of 30 = (4/5) * (30/1) = 120/5 = 24
Do the others the same way.
You'll need to change the mixed numbers to improper fractions.
2 3/7 = 17/7
thanks
You're welcome.
To find the product for each of the given expressions, you need to multiply the given numbers.
14.4/5 of 30 can be calculated as follows:
Step 1: Divide 30 by 5 to get 6 (since 30 divided by 5 is 6).
Step 2: Multiply 6 by 14.4 (since 14.4 is the numerator). The product is 86.4.
So, the answer to the first question is 86.4.
For the second question:
14 * 3/5 can be calculated as follows:
Step 1: Multiply 14 by 3 to get 42 (since 14 multiplied by 3 is 42).
Step 2: Divide 42 by 5 to get 8.4 (since 42 divided by 5 is 8.4).
So, the answer to the second question is 8 2/5.
For the third question:
3/10 * 2/10 can be calculated as follows:
Step 1: Multiply the numerators (3 and 2) to get 6 (since 3 multiplied by 2 is 6).
Step 2: Multiply the denominators (10 and 10) to get 100 (since 10 multiplied by 10 is 100).
Step 3: Write the product as a fraction: 6/100.
This fraction can be simplified by dividing the numerator and denominator by the common factor of 2. Hence, you get 3/50.
So, the answer to the third question is 3/50.
For the fourth question:
-4 1/3 * 1 3/5 can be calculated as follows:
Step 1: Convert the mixed numbers to improper fractions.
-4 1/3 = -13/3 and 1 3/5 = 8/5.
Step 2: Multiply the numerators (-13 and 8) to get -104 (since -13 multiplied by 8 is -104).
Step 3: Multiply the denominators (3 and 5) to get 15 (since 3 multiplied by 5 is 15).
Step 4: Write the product as an improper fraction: -104/15.
This fraction can be simplified, but let's leave it as an improper fraction for now.
So, the answer to the fourth question is -104/15.
For the fifth question:
2 3/7 * 2/3 can be calculated as follows:
Step 1: Convert the mixed number to an improper fraction.
2 3/7 = 17/7.
Step 2: Multiply the numerators (17 and 2) to get 34 (since 17 multiplied by 2 is 34).
Step 3: Multiply the denominators (7 and 3) to get 21 (since 7 multiplied by 3 is 21).
Step 4: Write the product as an improper fraction: 34/21.
This fraction can be simplified by dividing the numerator and denominator by the common factor of 2. Hence, you get 17/10.
So, the answer to the fifth question is 1 7/10.
Therefore, the respective answers to the given questions are:
14.4/5 of 30 = 86.4 (choice D)
14 * 3/5 = 8 2/5 (choice C)
3/10 * 2/10 = 3/50 (choice A)
-4 1/3 * 1 3/5 = -104/15 (choice B)
2 3/7 * 2/3 = 1 7/10 (choice A)
