Question

plz help me with all these answers !!

Answer 1

hey mate
here's ur answer

a)lcm if 5 and 7 is 35
$\frac{3}{5} \times \frac{7}{7} = \frac{21}{35}$

$\frac{4}{7} \times \frac{5}{5} = \frac{20}{35}$

$\frac{21}{35} \: \: \frac{20}{35}$

b)lcm of 4 and 5 is 20
$\frac{1}{4} \times \frac{5}{5} = \frac{5}{20}$

$\frac{1}{5} \times \frac{4}{4} = \frac{4}{20}$

$\frac{5}{20} \: \: \frac{4}{20}$

c) convert the mixed fraction
$1 \frac{1}{2} = 1 \times 2 + 1 \div 2 = \frac{3}{2}$

$4 \frac{1}{5} = 4 \times 5 + 1 \div 5 = \frac{21}{5}$

lcm of 2 and 5 is 10
$\frac{3}{2} \times \frac{5}{5} = \frac{15}{10}$

$\frac{21}{5} \times \frac{2}{2} = \frac{42}{10}$

$\frac{15}{10} \: \: \frac{42}{10}$
hope it helps
