Draw one ten, (If you have to draw ones, draw 3 of those) and the new fact is 10 + 3. (That equals 13, if you need that.)
A) The least common denominator is 12. Both 4 and 3 go into 12 evenly.
b) The least common denominator is 40. Both 5 and 8 go into 40 evenly.
Answer:
7
Step-by-step explanation:
I assume that 3,14 is 3.14
=3.14 x (200-175)2 - 150
=3.14 x (25)2 - 150
=3.14 x 50 - 150
=157-150
=7
Sum of 2 and 8 is (2+8)
Then multiply by 5 will give us answer a. (2+8)x5
