Question

7/12+4/36=

15/27-1/9=

11/14-1/7=

12/15-3/5=

15 7/24+8 1/3=

Answer 1

7/12+4/36=21/36+4/36=25/36

15/27-1/9=15/27-3/27=12/27=4/9

11/14-1/7=11/14-2/14=9/14

12/15-3/5=12/15-9/15=3/15=1/5

15 7/24+8 1/3= 15 7/24 + 8 8/24=23 15/24

Answer 2

$frac{7}{12} + frac{4}{36} = frac{7 times 3}{12 times 3} + frac{4}{36} = frac{21}{36} + frac{4}{36} = frac{25}{36}$
$frac{15}{27} - frac{1}{9} = frac{5}{9} - frac{1}{9} = frac{4}{9}$
$frac{11}{14} - frac{1}{7} = frac{11}{14} - frac{2}{14} = frac{9}{14}$
$frac{12}{15} - frac{3}{5} = frac{4}{5} - frac{3}{5} = frac{1}{5}$
$15 frac{7}{24} + 8 frac{1}{3} = frac{15 times 24 + 7}{24} + frac{8 times 3 + 1}{3} = frac{367}{24} + frac{25}{3} = frac{367}{24} + frac{200}{24} = frac{567}{24} = frac{189}{8} = 23 frac{5}{8}$
