Studdy Solution

STEP 1

Assumptions1. The problem states "Two-fifths of a number is -12." This implies that the number when multiplied by/5 gives -12.

STEP 2

Let's represent the unknown number as x. We can write the problem as an equation25x=−12\frac{2}{5}x = -12

STEP 3

To solve for x, we need to isolate x. We can do this by multiplying both sides of the equation by the reciprocal of2/5, which is5/2.
x=−12×52x = -12 \times \frac{5}{2}

STEP 4

Now, let's calculate the value of x.
x=−12×2=−30x = -12 \times \frac{}{2} = -30So, the number is -30.
