Question

If 7 × 3 ÷ 8 stand for 80 then 8 ÷ 2×9 will stands for what​

Answer 1

Answer:

88

Explanation:

Observe the equation and its respective output carefully. The first equation is -

7×3÷8 =80

To get the output of above mentioned equation as 80 we have to try different probablities. By looking at it we can understand that if we replace operator ‘×’ by ‘+’ and ‘÷’ by ‘×’ our equation becomes 7+3×8. But this isn’t enough as according to operator precedence multiplication comes first. Hence our output will be 31. So we need to introduce brackets in this equation, so that it will give us the desired output. Lets reframe the equation as -

(7+3)×8 = 80

Now consider the 2nd equation

8÷2×9

In this equation too we will replace the operators. So our 2nd equation becomes 8*2+9. Now here the question comes where to put brackets. Observing the pattern of our 1st equation where the brackets were for ‘+’ operator. We will put the brackets in 2nd equation too for ‘+’ operator. Lets reframe the equation as -

8*(2+9) = 88

So 8÷2×9 stands for 88

Answer 2

Explanation

8×2+9=25
