Mary has a spool of ribbon to make bows. She uses 3 8 yard of the spool's ribbon to make a bow. She has 1 4 yard of the ribbon left on the spool. Which choice is the MOST reasonable tor the yards on the spool before Mary made the bows? A) 3 8 yard
B) 1 2 yard
C) 5 8 yard
D) 5 6 yard

5/8 yards

Step-by-step explanation:

Amount Used: 3/8 yard

Amount Remaining : 1/4

Amount started with  = Amount Used + Amount Remaining

We need to find the common denominator for 8 and 4.

3/8 stays 3/8, and 1/4 becomes 2/8    (multiply the numerator and                      

                                                                denominator of 1/4 by 2)

3/8 + 2/8 = 5/8

b) 5/8 yard

Step-by-step explanation:

3/8 of the spool is used to make a bow.

She has 1/4 left. 1/4 = 2/8.

2/8 + 3/8 = 5/8

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
