45 + 5= ? -100.The missing number is

The missing number is 150

Step-by-step explanation:

45 + 5= ? -100

To carry out the problem we are going to call x to (?)

45 + 5= x -100

we see that we have a -100 of the second side of the equality, to get it out of there we can add 100 in both parts of the equality

45 + 5 + 100 = x -100 + 100

now we just solve and we have left

45 + 5 + 100 = x

As we see this is a common sum, by which we can already add it and obtain the value of x

150 = x

13.33%

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%
