Since they are similar you need to start by making ratios for each pentagon.
1.8/2.4 is the first and x/3.6 is the second. Now set them equal to each other and cross multiply.
1.8 X
___ = ____
2.4 3.6
2.4x= 6.48 Now divide both sides by 2.4
2.4x= 6.48
___ ____
2.4 2.4
X= 2.7
the answer to 1188/33 is 36
Answer: The LCM of 15 and 6, so the least common multiple, the smallest multiple that they have in common, we see over here. 15 times 2 is 30. And 6 times 5 is 30.
3d = 255
d = 85
d85 = x
d is the number of days, x is the amount of earnings.
5(85) = x
425 = x
