Let's divide this question into two parts:
1. Choosing any 3 digit number.
2. Find the number that is 10 more.
1. Let choose the number 111. As you can see it is the three digit number.
2. Now to find the 10 more to 111, we have to add 10 to 111 as follows:
111
+10
--------
121
Hence, the 10 more to the number 111 is 121.
Answer:
Step-by-step explanation:
1a. 25/50 =x/100
25*100= 2500/50= 50
A= 50%
1b. 35/40 = x/100
35*100= 3500/40= 87.5
A=87.5%
2a. 15/20= x/100
20*5= 100; 15*5= 75
A=75%
2b. 25/70= x/100
25*100= 2500/70= 35.71
A=35.71
3a. 15/80= x/100
15*100= 1500/80=18.75
A=18.75%
3b. 30/60= x/100
30/60= 1/2;1/2=0.5;0.5= 50%
A=50%
4a. 70/80 =x/100
70*100=7000/80 =87.5
A=87.5
4b.30/60 = 50% ( same as question #3b)
