Question

What is the value of the expression

m+(7*9)/n
when m = 2.5 and n= 5
a 6.3
b 9.5
c 11.9
d 13.1

Answer 1

We can substitute m = 2.5 and n = 5 into the expression:

m + (7*9)/n = 2.5 + (7*9)/5

We can simplify the second term:

(7*9)/5 = 63/5

Substituting back into the expression:

m + (7*9)/n = 2.5 + 63/5

We can find a common denominator and add the terms:

2.5 + 63/5 = 12.5/5 + 63/5 = 75/5 = 15

Therefore, the value of the expression is 15, which corresponds to option (b) as the correct answer.
