Ivan forgot to follow PEMDAS
Division first
12/3 = 4
4 x 2 = 8
8 + 8 = 16
Hope this helps!
Divide 2 from both sides
t < 5/2
Hope this helps!
The other factor is eight because 9 multiplied by eight is 72 and a negative times a positive is a negative
3.01 is the decimal notation for 3 1/100. You keep the three in the ones place. 1/100 is a decimal. If you use long division or a calculator, you can see that 1/100 is 0.01.
10/9 can be rewritten as 1 1/9, so it's closest to 1. 2/15 is really small, so close to 0.
