Question

aleena cuts 3/8 part of ribbon for her project then she agian cuts 4/5 part of the remaining ribbon find rhe length of ribbon if 6.5m of ribbon still remains
​

Answer 1

Answer:

the answer is :

Let's figure out how much of the ribbon has been cut.

 Let x = the original length of the ribbon

 Aleena initially cuts 3/8 of the ribbon, or a length of (3/8)x. How much is left? 1 - (3/8)x = (5/8)x.

 On the next day, she cuts 4/5 of the remaining ribbon. That is (4/5) * (5/8)x = (20/40)x = (1/2)x

 (3/8)x + (1/2)x = (3/8)x + (4/8)x = (7/8)x

 That means that 1 - (7/8)x = (1/8)x remains, and that is a length of 6.5 m.

1/8 of which number is 6.5?

 Let y = the unknown number.

 (1/8)y = 6.5

 Multiply both sides of the equation by 8 to clear the fraction.

 y = 52 m
