Answer:

Cross Multiplying.

Step-by-step explanation:

By multiplying each ratio by the second number of the other ratio, you can determine if they are equivalent. Multiply both numbers in the first ratio by the second number of the second ratio. For example, if the ratios are 3:5 and 9:15, multiply 3 by 15 and 5 by 15 to get 45:75.

How do you round with 5,900
vesna_86 [32]

Answer:

Well If there are answer choices please place them in the comments. But if there are not, that's okay. I'd say that you'd just keep it at 5,900 if you are trying to round to the nearest hundred. If you are trying to round to the nearest thousand, 6,000 would be right.

Remember, if the number is or is between 1 and 5 round down but if it is or is between 5 and 9, round up.
