Answer 1

Answer:

1=13

2=368

3=1537

4=1680.7

5=3110

6=15610

7=362

8=307

9=05

10=00.8

11=090

Step-by-step explanation:

If there is *10 with any number which has a decimal number then skip the point one number as in 10 there is one zero.

for eg=12.1*10 ten has one zero so skip the point one number and the ans will be 121.

Same like *100 with any number then skip the point 2 number as 100 has 2 zeroes .for eg=12.1*100=1210 we skipped one number and now there is no number that we can skip two times so we will write0.answer will be=12.1*100=1210.Same step with* 1000,*1000000 when multipliedwith any no.
