Explanation

Step 1: Translate the statement into an equation

“One-fourth of one-third of two-fifths of a number is 15”

$1 \times 1/3 \times 2 \times x = 15$

Step 2: Multiply fractions

$1 \times 1 \times 2/ 4 \times 3 \times 5 =2/ 60 = 1/ 30$

So,

$1/30 x = 15$

Step 3: Solve for x

$x = 15 \times 30 = 450$

So, the number is

$x = 450$

Step 4: Find 40% of the number

$40% of 450 = 40/100 \times 450$ $= 0.4 \times 450 = 180$
