The answer to this question would be: 1 5/6
To change a decimal number into fraction, you need to divide the number on the right of decimal point with 1. In this case, the number is 0.83.
This number is hard since .83 doesn't have many factors. To find the answer you can try to multiply the decimal with some number until it close to 1(no decimal left)
0.83* 2= 1.66
0.83* 3= 2.49 ---> close to half, if you find this number, you can try to double it
0.83* 4= 3.32
0.83* 5= 4.15
0.83* 6= 4.98---> close to 1, that means there is high probability that the number can be divided by 6
0.83 would be 4.98/6, but if we assume that the number is 0.8333...... then 0.83 would be 5/6. So, 1.83 would be 1 5/6
Answer:
7
Step-by-step explanation:
It would be 67,437,000,000 since the eight in 67,436,(8)28,104 rounds the 6 up to a 7.
First off all, let's find
.
This shows that Bai found the correct quotient.
If
, then
. Using this rule, you have to check that
is equal to product
