Answer:
To round 42.052 to the nearest hundredth consider the thousandths' value of 42.052, which is 2 and less than 5. Therefore, the hundredths' value of 42.052 remains 5.
(8/13+4/13)+(-6+8) < first one
(8/13+4/13)+(-6+8) and then you add the terms
60 min in an hour right? 30 miles means 1 hr. 180/30 = 6. 6 is the number of hr it took to travel 180 miles. make sense?
There are a couple of ways to look at this.
1) Set up a ratio: 2 cups sugar to 5 cups flour = 5 cups sugar to x cups flour
2/5 = 5/x
cross multiply
2x = 25
x = 12 1/2 cups flour
2) Look at the factor by which the cups of sugar was increased and increase
the cups of flour by the same factor.
2x = 5
x = 2.5
The sugar was increased by a factor of 2.5 so increase flour by same factor.
5(2.5) = 12 1/2 cups flour
