In at least 4 sentences explain the steps in subtracting fractions with unlike denominators you must use complete sentences solve 5/8 - 2/5

the final answer is 9/40

When subtracting fractions with different denominators, we follow the same process we used for adding unlike fractions. to work the problem using what's called the Least Common Denominator (LCD).

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
