(b) 0.308 to the second decimal place.​

Answer 1

Answer:

What's the unit here?

Otherwise Multiplying 5"(ft) 83(inch) with two gives 143(inches) X 2= 286 inches i.e., 7"26

a. 18.436

b. 0.31

Step-by-step explanation:

rounding a number to a certain place value needs look at the digit to the right of that place value and make the decision. So, when we see 7(>5) to the right of 5, then 5 will be incremented with 1 level up i.e., 6. Same rule for b. also...

Hope it works
