Hi
Today we are gonna be solving problems by rounding and compensating. To round and compensate you need a question, here's an example, 3 x 5 so five times three equals 15 right then you use 3 x 5 to help with all your three times tables like this, 3 x 6 you can solve it by just adding another three then you get your answer here's more examples.
to figure out we will need to round then compensate so 49 x 7 but instead we use 49 x 6 then if we don't know that then we use 49 x 5 so we should know that we just need to x 5 lots of times. so that equals 245 so now we 245 + 98=345. so now that we know how to round and compensate the answers should be.
49 x 7=345
58 x 9=522
208 x 1=208
92 ÷ 4=23
104 ÷ 8=13
64 ÷ 4 =16
