Step-by-step explanation:
you would do $12,600 / 7,100 and that would be estimated to the nearest hundredth 1.77
90,000
the reason is because look at the 1,000 place that rounds the 10,000 place to 0 and carries the 1 over to the 100,000 place
Sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. Then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
Answer:
the answer is 42
Step-by-step explanation:
Here is the solution...
Compensation
The compensation is nothing but the process of reforming the given expression to find the answer mentally.
Here we need to rewrite the given expression in order find the answer mentally.
<u>Step 1:</u>
Here we can add 8 with 6572, so we get 6580.
<u>Step 2: </u>
Add 8 from 239, so we get 247.
<u>Step 3:</u>
We can rewrite 247 as 240 + 7
<u>Step 4:</u>
Now we can subtract 240 from 6580, so we get 6340.
We can calculate this mentally.
<u>Step 5:</u>
Finally, we can subtract 7 from 6340 mentally, So we get
6333.
Mathematically, the above expression written as
6572- 239
= 6572 + 8 - (239 + 8)
= 6580 - 247
= 6580 - (240 + 7)
= 6580 -240 - 7
= 6340 - 7
= 6333
