What is 6 and 2 thirds minus 2 and 4 fifths?

Answers

Answer:

58/15

Step-by-step explanation:

Step 1: Convert words into an expression

6 and 2 thirds minus 2 and 4 fifths

6 2/3 - 2 4/5

Step 2: Make common denominator aka 15

6 2/3 = 6*3/3 + 2/3 = 18/3 + 2/3 = 20/3

20*5 / 3*5 = 100/15

2 4/5 = 2*5/5 + 4/5 = 10/5 + 4/5 = 14/5

14*3 / 5*3 = 42/15

Step 3: Subtract

100/15 - 42/15

58/15

Answer: 58/15
