Question

Find the missing number: 8.4(1.5 + 2.3) = 12.6 +

Answer 1

Answer:

19.32

Step-by-step explanation:

One way to find the missing number is to get the value of the left side of the equation first.

8.4(1.5 + 2.3) = 31.92

Now we need to take that value and subtract it to the value on the right side of the equation.

31.92 - 12.6 = 19.32

So we have:

8.4(1.5 + 2.3) = 12.6 + 19.32

31.92 = 31.92

Answer 2

Answer:

The required number is 19.32

Step-by-step explanation:

Consider the provided expression.

Let the missing number is x.

$8.4(1.5 + 2.3) = 12.6 +x$

Add the numbers as shown.

$8.4(3.8) = 12.6 +x$

Open the parentheses.

$31.92= 12.6 +x$

Subtract 12.6 from both the sides.

$31.92-12.6= 12.6-12.6 +x$

$x=19.32$

Hence, the required number is 19.32
