Question

When subtracting 7.6 from my certain number the result is 48.99, as seen below. What number should go in the box to complete the subtraction problem?

Answer 1

Answer:

The answer for the blank is;

$6$

Explanation:

we want to find the numerical value expected to be in the blank space;

let x represent the number;

calculating the subtraction;

9-0 =9

next;

we will borrow 1 from x so we will have;

15-6 =9

next

we heve;

10+(x-1) -7 =8

solving the equation we have;

$\begin{gathered} 10+x-1-7=8 \\ x+10-1-7=8 \\ x+2=8 \\ x+2-2=8-2 \\ x=6 \end{gathered}$

Therefore; subtracting 7.6 from 56.59 we will get 48.99.

The answer for the blank is;

$6$
