Question

By what number should 2 3/5 be multiplied to get 1 6/7 ?

Answer 1

Answer:

0.4

Step-by-step explanation:

23/5*x=16/7

x=0.4

Answer 2

Given - Mixed fraction

Find - Number

Solution - Let the number be x.

Converting mixed fraction to proper/improper fraction.

Fraction 1 = $2 \frac{3}{5}$

Fraction 1 = $\frac{(5 \times 2) + 3}{5}$

Fraction 1 = $\frac{10 + 3}{5}$

Fraction 1 = $\frac{13}{5}$

Fraction 2 = $1 \frac{6}{7}$

Fraction 2 = $\frac{(7 \times 1) + 6}{7}$

Fraction 2 = $\frac{7 + 6}{7}$

Fraction 2 = $\frac{13}{7}$

Forming the equation to find the value of x.

13/5*x = 13/7

Shifting 13/5 to Right Hand Side

x = (13/7)/(13/5)

Solving mentioned equation for the value of x.

x = (13*5)/(13*7)

Cancelling 13 in both numerator and denominator

x = 5/7

Hence, multiplication of 5/7 with 13/5 will give the result 13/7.
