Step-1: ◆The numbers that can divide 75 without remainder are called 75's factors. ◆Rule-1: N's factor is the number that can divide N without remainder. ◆Notice that the factors always includes 1 and itself. Step-2: Notice that the factors always includes 1 and itself. So,the factors of 75 are 1, ............75. ●A simple way is to find what pairs of numbers multiply to get 75. ●75=1×75 75 is divisible by 1 and 75 without any remainder.So,1 and 75 are the two factors of 75. Proofs: ●75/1=75 ●75/75=1 ...
Consider the two impoper fractions 7/3 and 5/2 to understand how to divide improper fractions with different denominators.Remember that in improper fraction,the numerator is always greater than denominator. ●7/3 divided by 5/2 =7/3 ÷ 5/2 (Translating) =7/3 × 2/5(Change of division sign and multiplied by the reciprocal fraction) Keep Change Flip method =(7×2)/(3×5) [Multiply top to top and bottom to bottom) =14/15 The answer for 7/3 divided by 5/ 2 is 14/15. So from the above example ,you know how to divide an improper fraction by another improper fraction. Next
169 cm in feet is equal to 5.54 feet. Explanation: 169 cm in feet We will convert 169 cm to feet in just five steps: Step-1: Rewrite 169 cm like the following. 169 cm =169 × 1cm .....(1) Step-02: Now we have to find out the value for 1 cm from basic equivalence between inch and cm. Remember that there is a equivalence between feet and inch. 1 inch = 2.54 cm Or, 1 inch =2.54 × 1cm Divide both side by 2.54 Or, 1 inch/2.54 = 1cm ..........(2) 169 Cm in Feet||169 Cm to Feet Step-3: From (1) and (2), 169 cm =169×(1 inch/2.54) = 66.54 inch(Rounding) Therefore,169 cm= 66.54 inches. •[169 cm to inches is equal to 66.54 inches]. Just rewrite, 169 cm =66.54 × 1 in....
