4 1/2

Step-by-step explanation:

41−172=?

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(4/1, 17/2) = 2

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(41×22)−(172×11)=?

Complete the multiplication and the equation becomes

82−172=?

The two fractions now have like denominators so you can subtract the numerators.

Then:

8−172=−92

This fraction cannot be reduced.

The fraction

−92

is the same as

−9÷2

Convert to a mixed number using

long division for -9 ÷ 2 = -4R1, so

−92=−412

Therefore:

41−172=−412

Solution by Formulas

Apply the fractions formula for subtraction, to

41−172

and solve

(4×2)−(17×1)1×2

=8−172

=−92

Convert to a mixed number using

long division for -9 ÷ 2 = -4R1, so

−92=−412

Therefore:

41−172=−412
