How do you simplify the fraction 18/72

1/4

Step-by-step explanation:

Find the GCD (or HCF) of numerator and denominator GCD of 18 and 72 is 18

Divide both the numerator and denominator by the GCD 18 ÷ 18 / 72 ÷ 18

Reduced fraction: 1 / 4 Therefore, 18/72 simplified to lowest terms is 1/4.

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.
