Question

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?

Answer 1

No she is not right like someone already said she needs 3/8 more

Answer 2

she needs 3/8 more than what she said

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
