When multiplying fractions, multiply the numerators (top part of fraction) with numerators and denominators (bottom part of fraction) with denominators.
Answer:
16
Step-by-step explanation:
Lets assume x is Elgas' age
And y is Alvins age
we know that alvin is 11 years younger than Elga which means,
x=y+11
and the sum of their age is 43
x+y=43
solve it and you get 16
0 is the point of origin because it's not really a number, it's more of a starting point for positive and negative numbers.
I think it’s Step C. Hope i’m right!
