1) d - c is calculated as; -4
2) Simplifying ³/₄ - ²/₅ gives; 7/20
What is the solution to basic arithmetic?
1) We are given;
c = 12 and d = 8. Thus;
d - c is calculated as;
8 - 12 = -4
2) We want to simplify ³/₄ - ²/₅
Factoring out 1/20 gives;
1/20(15 - 8) = 7/20
3) Number of pencils purchased = 888 pencils
Number of pencils in a box = 12
Thus;
Number of boxes purchased = 888/12 = 74 boxes
4) An integer is a whole number (not a fractional number) that can be positive, negative, or zero. The only one that is not an integer here is; 20/6
5) √64 = 8
6) (30 - 4 * 2)/(2 * 2²)
= (30 - 8)/8
= 22/8 = 11/4
7) 11 = x + 19
x = 11 - 19
x = -8
