Question

1.a:1 2/3 b..jika selisih a dan b 56 berapa nilai masing masing..
2.1 1/3 b,.,.jika a+b=63....tentukan nilai masig masing?

Answer 1

1).
a=1⅔b=5b/3

a-b=56
5b/3 - b =56
5b/3 - 3b/3 = 56
2b=56x3
2b=168
b=168/2
b=84

a-b=56
a=56+b
a=56+84
a= 140

jadi a=140 dan b=84

2).
a=1⅓b=4b/3

a+b=63
4b/3+b=63
4b/3 + 3b/3=63
7b=63 x 3
7b=189
b=189/7
b=27

a+b=63
a=63-b
a=63-27
a=36

jadi a=36 dan b=27
