Question

Please solve with explanation

Answer 1

Step-by-step explanation:

$4\frac{9}{20} - 1\frac{2}{6} =\\\frac{89}{20} - \frac{8}{6} = \frac{89 - 26.7}{20} = \frac{62.3}{20}$

$4\frac{6}{9} - 3\frac{3}{6} =\\\frac{42}{9} - \frac{21}{6} = \frac{252 - 189}{54} = \frac{63}{54} = 1\frac{9}{54}$

$2\frac{2}{4} - 1\frac{1}{3} =\\\frac{10}{4} - \frac{4}{3} = \frac{30 - 16}{12} = \frac{14}{12} = 1\frac{2}{12}$

Answer 2

Answer:

4 9/20 - 1 2/6 =

Exact form : 187/60  

Decimal form : 3.116 (place a line over the six to show that six is repeating itself many times. It will look like this... 3.116666666...)

Mixed Number form : 3 7/60

4 6/9 - 3 3/6 =

Exact form : 7/6

Decimal form : 1.16 (place a line over the six to show that six is repeating itself many times. It will look like this...1.166666666...)

Mixed Number form : 1 1/6

Step-by-step explanation: (For both answers...) Convert the mixed numbers to improper fractions, then find the LCD (Least Common Denominator) and combine.
