Answer is 17/50
Step-by-step explanation: 34/100 = 17/50 easy :D
Step-by-step explanation:
4 consecutive odd integers means we start with x, then have x+2, x+4 and then x+6.
and then we have
-24 = x + x+2 + x+4 + x+6 = 4x + 12
4x = -36
x = -9
x+2 = -7
x+4 = -5
x+6 = -3
so, in sequence from small to large these 4 numbers are
-9, -7, -5, -3
It is given that,
→ Mary has 55 pens.
→ Frazer has 12 pens.
We have to,
find what is the difference.
The formula we use,
→ Mary's pens - Frazer's pens
Let's subtract,
→ 55 - 12
→ 43 pens
Hence, difference is 43 pens.
