Question

Yovani can do 8 math problems in 1 3/5 of a

minute. How many problems can he
complete per minute?

Answer 1

5 Problems

Explanation:

Based on the given conditions, formulate:
`8` ÷
`1(3)/(5)`

Find common denominator and write the numerators above common denominator:
`(8)/((5)/(5) +(3)/(5) )`

Write the numerators over common denominator:
`(8)/((5+3)/(3) )`

Calculate the sum or difference:
`(8)/((8)/(5) )`

Divide a fraction by multiplying its reciprocal: 8 ×
`(5)/(8)`

Cross out the common factor: 5

get the result: 5

Answer: 5
