So basically, first just do this step by step, or subtract 38 from 26 first.
26 - 38 is basically -(38 - 26), or -12.
So then, it becomes -12 + (-3)
A - and a + becomes - because you're adding negative 3.
-12 - 3
Which then becomes -15.
2/5 + 5/6
Start with the denominator
To compare or combined they must be the same kind. Basically the bottom numbers have to be the same.
5 x 6 = 30
Now go across from the bottom number to the top
5 x 5 = 25
6 x 2 = 12
12/30 + 25/30 = 37/30
Answer:
3 x 5= 15
Step-by-step explanation:
If you count by 5's like 5, 10, 15, 20
And if you count by 3's: 3, 6, 9, 12, 15
then find the least common multiple and it is 15
