Step-by-step explanation:
1)
1000000= 1 million
100000= 1 hundred thousand
to make hundred thousand into million we have to have multiply it by 10
= 10 Ans
2) 0 Ans
3) non prime or composite number Ans
4)
272 -198 = 74 Ans
5) plane Ans
6) reciprocal Ans
7) unlike fraction Ans
8)1, fraction Ans
9) I can't understand it sorry
10) thousandths Ans
true or false
a) false b) false c) true d) true
11) 12× 75
= 12×(70+5) multiply 12 by 70 and 5
= 840+60= 900 Ans
12) 25×1963×4
= 100×1963=196300 Ans

22) -10- 4 = -6 Ans
23) 1296×96÷864= 124416÷864 = 144 Ans
24) divisbility rule of 2 = if the number ends with 0,2,4,6 then it is divisible by 2
divisbility rule of 3 =if the sum of all numbers is the multiple of 3 then it is divisible by 3
divisbility rule of 4 = if it's last two digit is divisible by 4 then the whole number is divisible by 4
divisbility rule of 5 = if it's last digit is 0 or 5 then it is divisible by 5
divisbility rule of 6 = if the number is divisible by 2 and 3 then it is divisible by 6
the 45880 is divisible by 2,4 and 5 Ans
