It seems like you have the answer already. but heres how its calculated.
\frac{100}{15} = \frac{?}{3} 
so the missing number is 20 **cross multiply 100 and 3 to get 300 then divide 15 into 300 to get 20**

\frac{160}{100} =  \frac{80}{?} 
so the missing number is 50
 **cross multiply 100 and 80 to get 8000 then divide 160<span> into 8000 to get 50**</span>

Someone help me pls <br><br>47 as the sum of ______
Elanso [62]

9514 1404 393

Answer:

  (a) 6² +3² +1² +1² = 47

  (b) 5² +4² +2² +1² +1² = 47

  (c) 3³ +4² +2² = 47

Step-by-step explanation:

It can work reasonably well to start with the largest square less than the target number, repeating that approach for the remaining differences. When more squares than necessary are asked for, then the first square chosen may need to be the square of a number 1 less than the largest possible.

The approach where a cube is required can work the same way.

(a) floor(√47) = 6; floor(√(47 -6^2)) = 3; floor(√(47 -45)) = 1; floor(√(47-46)) = 1

__

(b) floor(√47 -1) = 5; floor(√(47-25)) = 4; ...

__

(c) floor(∛47) = 3; floor(√(47 -27)) = 4; floor(√(47 -43)) = 2
