We can think of this as a right triangle, where the given lengths are the legs.

So, we can solve using the Pythagorean Theorem.

21² + 28² = c²

441 + 784 = c²

Daily twos:

Answer:

  9 3/4

Step-by-step explanation:

Strategy: first cancel the fraction part of the mixed number, then subtract the remaining fraction from the integer obtained.

10 1/2 - 3/4 = 10 1/2 - 1/2 - 1/4

= 10 -1/4

= 9 3/4

__

Strategy: turn the subtracted fraction into a whole number by adding 1/4 to both parts of the problem, then subtract the whole number.

10 1/2 - 3/4 = (10 1/2 +1/4) -(3/4 +1/4)

= 10 3/4 -1

= 9 3/4

_____

We assume that you know that 1/2 + 1/4 = 3/4, or 3/4 -1/2 = 1/4. If you need to, you can get there by using the equivalent: 1/2 = 2/4.
