Describe why you can change a subtraction problem into an addition problem
Elena-2011 [213]
A subtraction problem can be turned in to an addition problem because of negative numbers. Take 5-2=3 for example. If you change 5-2 into an addition problem then you would but he addition sign and a negative sign on 2. This will then leave you with the problem looking like 5+ -2. If you add 5 and -2 you will still get three.

A building contractor buys 7070​% of his cement from supplier A and 3030​% from supplier B. A total of 9595​% of the bags from A
tatiyna

Title:

<h2>The answer is \frac{133}{174}.</h2>

Step-by-step explanation:

Let the building contractor bought 1000 cement in total.

70% of 1000 = 700 cements were from A and (1000 - 700) = 300 cements were from B.

The number of undamaged bag from A was 95% of 700 = \frac{95}{100} \times700 = 7\times95 = 665 and the number of undamaged bags from B was 70% of 300 = \frac{70}{100} \times300 = 210.

Total undamaged bags were (665 + 210) = 870.

The probability that an undamaged bag is from A is \frac{665}{870} = \frac{133}{174}.
