Jason made the following calculations. Explain the errors Jason made. Give the correct answers. a. 1/3 + 3/5 = 4/8
b. 11/12 - 5/6 = 6/6 = 1

a. 14/15

b. 1/12

Step-by-step explanation:

a) 1/3 + 3/5

so find the lowest common multiple for the denominators which is 15

then say 15 ÷ 3 = 5

then 15 ÷ 4 = 3 (you are dividing by the denominators)

say 5 × 1 (multiple by the numerators now)

= 5

= 5/15

now say 3 × 3 = 9

= 9/ 15

now it's 5/15 + 9/15

= 14/15

Jason made an error that he just added the denominators without applying any formula.

b. 11/12 - 5/6

find the lcm

= 12

11/ 12 × 1/1 = 11/12

5/6 × 2/2 = 10/12

11-10

= 1

= 1/12

Jason made a mistake that he said 12-6 instead of finding the LCD them multiplying that fractions
