Answer:

2.3*10^-10

Step-by-step explanation:

2.3 because that number can never be higher than 10

-10 because there are 10 spots from where the decimal is to where it needs to be for it to be 2.3

-10 because the number is small

What is the difference in the size between 1/4 and 1 1/2
masya89 [10]
1 1/2 can be rewritten as 3/2
Difference means subtraction

So we do:
3/2-1/4
To get the same denominator, we can multiply the first fraction by 2
6/4-1/4

Then we subtract the numerators and leave the denominator
So the final answer is 5/4 of 1 1/4

Hope this helps

The cost of the hiking trip this year is 2/3 of the cost of last year's trip. This year's trip cost $32. Write an equation that
allsm [11]

Answer: (32/2)*3=48

Step-by-step explanation:

In order to find the answer, we must find one third of last year's trip. To do this, we can simply divide the cost of this years trip by two, 32/2=16.

Now if we multiply this this number by 3, 16*3=48, we can see that the total cost of last year's trip was $48.

If we'd like to turn this into one equation, it looks like this: (32/2)*3=48
