Question

fill in the blank:-
1.
$\frac{25}{30 } = \frac{25 \ \div }{30 \div 5} = \frac{5}{6}$
2.the lowest terms of
$\frac{12}{20 } \: is \:$
3.
$\frac{1}{3} + \frac{3}{5 } =$​

Answer 1

Answer:

1. 5 Because the denominator is divided by 5.

2.3/5 I have divided 12/20 by 4.

3. 14/15.

Answer 2

Step-by-step explanation:

Part 1

$\large \frac{25}{30} = \frac{25 \div x}{ 30 \div 5 } = \frac{5}{6} \\ \\ \large\frac{25}{30} = \frac{25 \div 5}{30 \div 5} = \frac{5}{6}$

Part 2

$\large \frac{12}{20} = \cancel{ \frac{12}{20} }= \frac{3}{5}$

3\5 is the lowest term.

Part 3

$\frac{1}{3} + \frac{3}{5} = \frac{3 \times 5 + 3 \times 3}{15} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: = \frac{5 + 9}{15} \\ \\ \: \: \: \: = \frac{14}{15}$
