To read 5-5/8 inches on the scale, first find the five inch mark, then determine the number of 32nds in 5/8. Find the edge marked 32 and once again look between the numbers “5” and “6”. However, precision measurements require smaller graduations.
Common tapes and rules usually are not graduated smaller than sixteenths. Use multiplication to solve the problems.
There are now 16 equal divisions between each inch. IEmily for your next exercise use the following picture of a ruler as a guide in answering the following questions. Now turn the ruler and look at the edge with a 16 marked on it. The lengths of these lines differ and indicate different fractions or parts of an inch.Įach half inch is divided in half by a slightly shorter line indicating 1/4 on the left and 3/4 on the right.Įach 1/4 inch is divided in half by the shortest line which indicates 1/8 inch. Look at the section between the “5” and the “6” on the edge marked with an “8” for eighths. FR-72 Carpenters Folding Rule Lightweight Composite Construction Ruler with Easy-Read Inch Fractions - 6.5ft / 2m. When referring to fractions, always use the reduced name. This numeral indicates the number of divisions per inch. If you want to measure the actual size of a small object in inches or centimeters and you don’t have a real ruler at hand, this virtual on-screen online ruler will help you. There is a small numeral marked on the end of the ruler (red numbers). The opposite side is similarly divided into 32 and 64 spaces per inch, and it is common practice to number every fourth division for easier reading. marks are commonly made longer than the smaller division marks to facilitate counting, but the graduations are usually not numbered individually, as they are sufficiently far apart to be counted without difficulty. Simplify the fraction to the smallest possible denominator. Complete the sum by multiplying the first fraction with the reversed second fraction. Flip the second fraction upside down, switching the nominator (top number) and denominator’s (second number) places. The other edge of this side is divided in sixteenths. Write out the whole sum, BUT replace the ÷ with an ×. On one edge each inch is divided into 8 equal spaces so each space represents 1/8 in.
