Answer 1

Step-by-step explanation:

QUESTION 3)

1. FIRST CHANGE ALL MIXD FRACTION TO IMPROPER FRACTION .
2. $\frac{5}{2} + \frac{7}{4} + \frac{1}{3}$
3. Then take out the Lcm of denominators . Which is 12 ( lcm of 2,3 and 4 ). Now make them equivalent Fractions
4. $( \frac{5}{2} \times 12) + ( \frac{7}{4} \times 12) + ( \frac{1}{3} \times 12)$
5. Then we will reduce all the fractions :
6. $(5 \times 6) + (7 \times 3) + (1 \times 4)$
7. THEN:
8. $30 + 21 + 4$
9. Answer =

$55$

QUESTION 4)

1. Again first we will change all mixed fractions into improper fraction

$\frac{5}{4} + \frac{5}{2} + \frac{13}{5}$

2. Then we will take out the lcm of 4,2 and 5 which is 20. And then we will Multiply it by all fractions to make it equivalent.

$( \frac{5}{4} \times 20) + ( \frac{5}{2} \times 20) + ( \frac{13}{5} \times 20)$

then:

$(5 \times 5) + (5 \times 10) + (13 \times 4)$

=

$25 + 50 + 52$

$127$
