4/10 divided by 5/8 ​
blsea [12.9K]

Answer: 16/25

<h2>Solution with Steps</h2>

4/10 divided by 5/8 = ?

Dividing two fractions is the same as multiplying the first fraction by the reciprocal or inverse of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes -

4/10 x 8/5 = ?

For fraction multiplication, multiply the numerators and then multiply the denominators to get -

Numerators: 4 x 8 = 32

Denominators: 10 x 5 = 50

Fraction: 32/50

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 32 and 50. The GCF (Greatest Common Factor) would be 2.

Numerator: 32 / 2 = 16

Denominator: 50 / 2 = 25

Fraction: 16/25

<h2>Another Solution</h2>

4/10 divided by 5/8 = ?

Cross multiply -

Numerator x Denominator: 4 x 8 = 32

Denominator x Numerator: 10 x 5 = 50

Fraction: 32/50

Reduce by dividing both the numerator and denominator by the Greatest Common Factor, which is 2.

Numerator: 32 / 2 = 16

Denominator: 50 / 2 = 25

Fraction: 16/25

It took Mark a total of 4 hours 40 minutes to clean the garage and cut the grass. If it took 1 hour 45 minutes to cut the grass,
Lady_Fox [76]
You can get the answer by subtracting the time it took Mark to cut the grass from the total amount of time it took him to do the chores. So 4 hours and 40 minutes minus 1 hour and 45 minutes is 2 hours and 55 minutes
