What should come in place of question mark (?) in the following questions? 1.5 × 78 ÷ 0.5 = ?
234
The question asks to find the value represented by the question mark (?) in the expression $1.5 \times 78 \div 0.5$. We need to perform the arithmetic operations following the standard order.
Multiply 1.5 by 78:
First, calculate the product of $1.5$ and $78$.
$ 1.5 \times 78 = \frac{3}{2} \times 78 $
$ = 3 \times \frac{78}{2} $
$ = 3 \times 39 $
$ = 117 $
Divide the result by 0.5:
Next, divide the result ($117$) by $0.5$. Dividing by $0.5$ is the same as multiplying by $2$.
$ 117 \div 0.5 = 117 \div \frac{1}{2} $
$ = 117 \times 2 $
$ = 234 $
The calculation $1.5 \times 78 \div 0.5$ equals $234$. Therefore, the question mark (?) should be replaced by $234$.
