Choose the equation that is equivalent to this statement: 4 is 80% of x Math item stem image CLEAR CHECK 4x=0.8 4=0.8x 4⋅0.8=x x4=80100

Answer 1

4 = 0.8x

Explanation:

We need to translate these into mathematical equations:

- "4 is"; "is" always means "=", so we have "4 = ..."

- "80%" is just 80/100 because remember that % means "out of 100"

- "of x"; "of" always means "×", so we use multiplication: "* x"

Put this altogether:

4 = (80/100) * x

80/100 = 8/10 = 0.8

4 = 0.8x

Answer 2

4=0.8x

Explanation:

4 = 80% of x

4 = 80/100 × x

4 = 0.8x
