Question

One fourth of one third of two fifth of a number is 15. what will be 40% of that number?

Answer 1

Answer:

18, hope this helps, please mark me as brainliest.

Step-by-step explanation:

LET THE NUMBER BE X

 so,

1/4×1/3×2/5×X=15

2/60×X=15

X=450

NOW 40%×450

=40/100×450

180 IS 40% OF THE NUMBER

Answer 2

Given - Number

Find - 40% of that number

Solution - Let the number be x. Representing the given information in mathematical equation -

$\frac{1}{4} \times \frac{1}{3} \times \frac{2}{5} \times x = 15$

Performing multiplication on Left Hand Side

$\frac{2}{60} \times x = 15$

Shifting 2/60 to Right Hand Side

$x = 15 \times \frac{60}{2}$

Performing division

$x = 15 \times 30$

Performing multiplication

$x = 450$

So, the number is 450.

40% of the number = $\frac{40}{100} \times 450$

Cancelling zero from numerator and denominator and performing multiplication

40% of the number = 180

Hence, the 40% of that number is 180.
