If you pay 2 cents for a slate-pencil, how many can you buy for 10 cents ? How many 2's are there in 10 ? 6. How many times is 2 contained in 10? Finding how many times one number is contained in another is called Division. The sign : is used to indicate division. It is read divided by. Thus the expression 8:4=2, is read 8 divided by 4 is equal to 2. 8. Read the following: 6=2=3; 8=2=4; 10 = 2=5; 12:3= 4. 9. At 2 cents apiece, how many lemons can be bought for 12 cents ? 12:2=? 10.
