In order to do this sum (without using a calculator) you must find the lowest common multiple of 5 and 4. It is 20. This means that the bottom part of both fractions must become 20. /20 + /20. For the top half, you must multiply the original top halves by what you multiplied the bottom halves. 1 X 4 = 4. 3 X 5 = 15. The question now becomes: 4/20 + 15/ 20. The answer is 19/ 20
Answer:
764x
Step by step explanation:
4^4=256
8^3=512
2^2=4
256-4+512=764
765x
THE ANSWER WOULD BE 5.5
EXPLANATION: AB IS 2.5 and DC IS 8
2.5 - 8 = 5.5
2 because if you have a square and draw a diagonal you get two triangles
