On the first day, a man did 3/35 of a job, on the next day he completed another of the job. What fraction of the job was left undone?

Sagot :

Answer:

just need to add those fractions but we must make them similar fractions because they don't have similar denominator.

LCD(8, 5) = 40

3/8 = 15/40

2/5 = 16/40

.

Now, let's add them and subtract to 1 to determine the fraction of the job undone.

1 - (15/40 + 16/40)

= 1 - 31/40

= 40/40 - 31/40

(Note: I used 40/40 to replace 1. Any number divided by itself is equal to 1.)

= 9/40
