Question

subtract 1/7 from_3/8​

Answer 1

Answer:

We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.

So we multiply 1 by 3, and get 3.

Then we multiply 2 by 7, and get 14.

Next we give both terms new denominators -- 7 × 3 = 21.

So now our fractions look like this:

3

21

−

14

21

Step 2

Since our denominators match, we can subtract the numerators.

3 − 14 = -11

So the answer i

Answer 2

Step-by-step explanation:

$\frac{3}{8} - \frac{1}{7} \\ lcm \: of \: 8and \: 7 = 56 \\ \\ \frac{3}{8} \times \frac{7}{7} = \frac{21}{56} \\ \frac{1}{7} \times \frac{8}{56} \\ \\ \frac{21}{56 } - \frac{8}{56} \\ = \frac{21 - 8}{56} \\ = \frac{13}{56} \\ \\ \\ \\ ur \: answer$

hope it helps you..
