Calculate [a.] 1/2 + 1/5 + 1/6 = [b.] 1/7 x 2 2/5 = [c.] 1/2 + 4 1/3 - 3 2/5 = [d.] 5/2 ÷ 7/2 - 1/5 = [e.] (1/2 + 2/3) ÷ 1/5 = send the answer as soon as possilbe plss i beg you all​

Conversion a mixed number 3 3/

4

to a improper fraction: 3 3/4 = 3 3/

4

= 3 · 4 + 3/

4

= 12 + 3/

4

= 15/

4

To find new numerator:

a) Multiply the whole number 3 by the denominator 4. Whole number 3 equally 3 * 4/

4

= 12/

4

b) Add the answer from previous step 12 to the numerator 3. New numerator is 12 + 3 = 15

c) Write a previous answer (new numerator 15) over the denominator 4.

Three and three quarters is fifteen quarters

Conversion a mixed number 2 2/

5

to a improper fraction: 2 2/5 = 2 2/

5

= 2 · 5 + 2/

5

= 10 + 2/

5

= 12/

5

To find new numerator:

a) Multiply the whole number 2 by the denominator 5. Whole number 2 equally 2 * 5/

5

= 10/

5

b) Add the answer from previous step 10 to the numerator 2. New numerator is 10 + 2 = 12

c) Write a previous answer (new numerator 12) over the denominator 5.

Two and two fifths is twelve fifths

Multiple: 15/

4

* 12/

5

= 15 · 12/

4 · 5

= 180/

20

= 9 · 20/

1 · 20

= 9

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(180, 20) = 20. In the next intermediate step, , cancel by a common factor of 20 gives 9/

1

.

In words - fifteen quarters multiplied by twelve fifths = nine.
