what is 11/8 x 40 maths homework?

So it's one-and-three-eighths times 40 which is 55

A whole number like 40 can be written as 40/1.

When multiplying fractions, you multiply the numerators together, and multiply the denominators together:

11/8 x 40/1 = 11x40 / 8 x 1 = 440 /8. Then simplify.

Another thing you can do, is simplify before you multiply. If you have 12/8, both of those numbers are divisible by 4, right? so you can divide each number by 4 and reduce 12/8 to 3/2.

For a multiplication problem, it's the same thing. You can look at the 40 in the numerator, and the 8 in the denominator. Do they have a common factor? Yep, 8. So the 40 can be crossed off and made into a 5, and the 8 crossed off and made into a 1:

11x40 / 8 x 1 = 11x5 / 1x1. That's eaiser to simplify.

Best of luck to you!

In fractions you multiply by multiplying the numerator by the numerator and of course denominator by denominator.

So:

11/8 x 40 is the same as 11/8 x 40/1

and so:

= 440/8

Simplify

= 55
answer is 55

basically 40 / 8 * 11 so 55

11 x 5 = 55

55

11 x 5 = 55

PS
11/8 IS a fraction and also means 11 divided by 8

11/8 x 40
= (11 x 40)/8
= 11 x 40/8
= 11 x 5
= 55

40 is a whole number since but it's multiplied to a fraction 11/8.We can put a 1 under 40 (because all whole numbers have 1 as their denominator) it will become 40/1.Therefore: 11/8*40/1.Then we move on to cancellation since 40 is a numerator and 8 is a denominator we can cancel them both by finding their GCF(common Greatest factor) which is 8. So 8 divided by 8 is 1 and 40 divided by 8 is 5. so the problem will become 11/1 * 5/1 now we can remove the denominator since its 1(because all whole numbers have 1 as their denominator)so 11 & 5 are now whole numbers.so multiply them 5 * 11 = 55

11/8 x 40

u simplyfy 8 and 40 to get 11/1 x 5 so the answer's 55 =)

It's a sum and if you divide 11 by 8 so you get a decimal fraction and times it by 40 you will get the same answer as if you times 11 eighths by 40.
