Answer: a) 2 b)1 c)1/3 d)5/4
Step-by-step explanation:
Hi to solve this equation we simply have to replace the variable with the number given, and then isolate the variable.
5 x 2/5 = 10 /5 = 2
5/5= 1
In this case after replacing the number we have to simplify it.
2 (2/3) -1 =
4 /3 -1 =
4/3 -3/3 = 1/3
In this case, to add fractions first we have to multiply the top and bottom numbers of the second fraction by 3, to have the same denominators.
1/2 + 3/4 =
2/4 +3/4 = 5/4
Feel free to ask for more if it´s necessary or if you did not understand something.
