Let's break down the given expression step by step:
"Two-fifths of one-fourth of three-sevenths of a number" can be written as:
(2/5) * (1/4) * (3/7) * x = 15
Now, let's simplify this equation:
(2/5) * (1/4) * (3/7) * x = 15
Multiply the fractions:
(2/5) * (1/4) * (3/7) = 6/140 = 3/70
Now, the equation becomes:
(3/70) * x = 15
To solve for x, we'll isolate x:
x = (15 * 70) / 3
x = 350
Now, you want to find half of the number, which is:
(1/2) * 350 = 175
So, half of the number is 175, which is the correct answer.
