Edmond wants his students to be well-prepared for their test. They will spend 1/5 of their review time on fractions and 6/7 of their review time-on decimals. How much longer will they spend on fractions than on decimals?
1/5 * 7 = 7/35
6/7 * 5 = 30/35
37/35 is more than a whole
Your question doesn't make sense.
Huh ?
1/5 = 0.20
6/7 = almost 1
in other words they spent more time on decimals by far.
Do you have a typo?
What is the total time anyway? You need that to get the difference.
by the way
1/5 + 6/7 = 7/35 + 30/35 = 37/35 which is more than all the time.
Something is very wrong with your problem statement.
Thank you I thought the same something was wrong. I’ll ask my teacher tomorrow.
To find the difference in time spent on fractions and decimals, we first need to determine the exact values of 1/5 and 6/7.
To calculate 1/5, we divide 1 by 5:
1 ÷ 5 = 0.2
To calculate 6/7, we divide 6 by 7:
6 ÷ 7 ≈ 0.8571
Now that we have the decimal values, we can compare the time spent on fractions and decimals.
The time spent on fractions is 0.2, and the time spent on decimals is 0.8571.
To find the difference, subtract the time spent on decimals from the time spent on fractions:
0.2 - 0.8571 ≈ -0.6571
The result is approximately -0.6571. Since negative time doesn't make sense in this context, we can conclude that they will spend more time on decimals than on fractions.
Therefore, they will not spend any time longer on fractions than on decimals.
