1/a = 1/b: cross multiplying gives a = b
(Simplify example with group symbols)5 x (2 + 7)Solution:5 x (2 + 7) = 5 x (9) (Add first addition inside parentheses)= 45 (Multiplied)("A x (B + C)" can also be written as "A(B + C)".(Simplify example without Group Symbols)5 x 2 + 7Solution:5 x 2 + 7 = 10 +7 (Multiply)= 17 (Add)

a=7 b=9 ab=? ab is the multiplication of a & b there fore the value of ab=7*9=63
This question is somewhat confusing. Do you mean it as (a) 25 over 35, or (b) 35 over 25? Here are the answers for both. (a) 25/35 = 5/7 or 0.714 (rounded) (b) 35/25 = 7/5 or 1+(2/5) or 1.4
(7/9)-(5/18)(14/18)-(5/18)(14-5)/189/181/2 ◄Rule: (a/b)-(c/d) = (ad-bc)/(bd)(126-45)/16281 / 1621 / 2 ■
Unless B is 9 or greater, 7/8 is closer to 1. I converted everything to decimals to help me decide.
68 = 7b - 9 -7b = -68-9 b = (-68-9)/-7 = 11
