Answer 1

2-1:1=1
1/2:1=1/2
1/3: 1 1/4=1/3:5/4=4/15
5 41/50 : 3/10- 1/8 x 1 3/5 =
=291/50 ×10/3-1/8 ×8/5=
=97/5-1/5=96/5

Answer 2

a. $2- \frac{1}{1} =2-1=1$

b. $\frac{1}{2} :1= \frac{1}{2}$

c. $\frac{1}{3} :1 \frac{1}{4} = \frac{1}{3} \frac{5}{4} = \frac{4}{15}$

d. $5 \frac{41}{50} : \frac{3}{10} - \frac{1}{8}1\ \frac{3}{5}$
$= \frac{291}{50} + \frac{10}{3} - \frac{1}{8} \frac{8}{5}$
$= \frac{97}{5} - \frac{1}{5}$
=$\frac{96}{5}$
