Question

Solve 4 1/4 - 2 11/20

Answer 1

This could be solved as a group of mixed numbers, but I like to work with improper fractions more.
17/4 - 51/20
Next, you need to find a common denominator.
85/20 -51/20
When adding and subtracting fractions, you only work in the numerator, and the denominator stays the same.
34/20
Then, you just simplify.
Improper fraction: 17/10
Mixed number: 1 7/10
Decimal: 1.7

Answer 2

$4\frac{1}{4} - 2\frac{11}{20}$
Change them into improper fractions by multiplying the denominator(bottom) by the whole number then adding the numerator
$\frac{17}{4}$ - $\frac{51}{20}$
You must have a common denominator
Multiply $\frac{17}{4}$ by $\frac{5}{5}$⇒$\frac{85}{20}$
$\frac{85}{20}$-$\frac{51}{20}$=$\frac{34}{20}$
Simplify by dividing the numerator by the denominator
34÷20=$1\frac{14}{20}$⇒$1 \frac{7}{10}$ reduced
You answer is $1 \frac{7}{10}$
