Jennifer needs 1/8 yard of red ribbon, 1/4 yard of blue ribbon, and 1/2 yard of green ribbon. She estimates that she needs about 1/2 yard of ribbon in all. Is she right? How close to the actual answer is her estimate?

she needs 3/8 more than what she said

Step-by-step explanation:

1/4= 2/8

1/2= 4/8

adding 1/8+2/8+4/8= 7/8

since 1/2= 4/8 she is wrong

she needs 3/8 more than what she said

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
