Question

Find the number if:

Answer 1

Answer:

162 and $\frac{5}{2}$

Step-by-step explanation:

To find the original number multiply by the reciprocal of the multiplier, that is

90 × $\frac{9}{5}$ = $\frac{810}{5}$ = 162

------------------------------------------------------------------------

Similarly

Change the mixed number into an improper fraction

5 $\frac{5}{6}$ = $\frac{35}{6}$ , then

$\frac{35}{6}$ × $\frac{3}{7}$ ( cancel 35 and 7 by 7 / cancel 6 and 3 by 3 )

= $\frac{5}{2}$ × $\frac{1}{1}$

= $\frac{5}{2}$

Answer 2

Answer:

162

Step-by-step explanation:

If it is 5/9 of the original number is 90 we can just divide 90 by 5 to find 1/9 and then we can multiply that with 9 to get 9/9 which is the whole number.

90 ÷ 5 = 18

18 × 9 = 162
