Estimate the value of 2.265 divided by 0.52.

The first thing we can say is that 2.265 is about two. Then we can say that 0.52 is about one-half. It’s about zero and five-tenths.

Now we have two divided by five-tenths. What if we take this five-tenths and we turned it into a fraction, five-tenths? Then we can recognize that five out of ten is the same as one out of two. It’s one-half.

Now we’re asking the question what is two divided by one-half. When we’re trying to divide by a fraction, we change the division to multiplication and then we flip the fraction. We turn one-half into two over one.

Now we say two times two over one. Two times two equals four. The estimate for 2.265 divided by 0.52 would be four.
