Monica tried to add 1 1/4 + 2/3 and got 1 3/7 as her answer. 1. Explain Monica’s error.

2. What is the correct answer to the problem?

NO LINKS

Step-by-step explanation:

When adding fractions of different denominators, first find the LCM of the denominators, but she ignored that.

11/4+2/3

LCM=12

(33+8)/12

41/12

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
