it is for what seems most people, but for other people it is easy
2 1 2 + 5 3 4 = 7 4 6
well you have to make sure both numbers have the same denominators
5 1/4 - 1 7/8
multiply 1/4 by 2/2
5 2/8 - 1 7/8
now subtract
3 3/8
and there's your answer!
p.s. dont forget when you borrow from the 5, instead of adding 10 you add the denominator so you would add 8
pretend you have 1 cookie. then your best friend comes and gives you another. how many cookies would you have? 2
0.45(d-1.2)+0.67=5.53
use distributive property
0.45d - 0.54 + 0.67 = 5.53
now combine like terms (0.54 + 0.67)
0.45d - 1.21 = 5.53
add 1.21 on both sides
0.45d = 6.74
now divide by 0.45 on both sides
d = 14.9777777778
which rounds to
d = 15
0 divided by 2 is 0
first turn 2 into a fraction
1/3 divided by 2/1
now use the recipricle and multiply
1/3 x 1/2
multiply across
1/6
there's your answer!
x - 13 = 9
add 13
x = 22
so -12/1 divided by 5/1?
use recipricle
-12/1 x 1/5
now multiply across
-12/5
simplify
-2 2/5
and there's your answer
2 + 2 = 4!
