3/4−2/5=7/20

Solution with Steps

3/4−2/5=?

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

LCD(3/4, 2/5) = 20

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.

(3/4×5/5)−(2/5×4/4)=?

Complete the multiplication and the equation becomes

15/20−8/20=?

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

Then:

15−8/20=7/20

This fraction cannot be reduced.

Therefore:

3/4−2/5=7/20

Solution by Formulas

Apply the fractions formula for subtraction, to

3/4−2/5

and solve

(3×5)−(2×4)/4×5

=15−8/20

=7/20

Therefore:

3/4−2/5=7/20

<span><span>1.       </span>There are many ways of solving this kind of division problem. But I will showing the easiest one.
15.75 divided by 0.25
=> In every 1 whole number, there are 4 of 0.25
Now we have 15 as whole number so simply multiply 15 x 4
=> 15 * 4 = 60, there are 60 pieces of .025s in 15.
=> 0.75 has 3 0.25s
Now, let’s add 60 + 3 = 63, the answer is 63.
There are 63 pieces of 0.25 in 15.75.
Let’s check
=> 15.75 / 0.25
=> 63</span>
