Jeff uses 3 fifth- size strips to model 3/5. he wants to use tenth size strips to models an equivalent fraction. how many tenth size strips will he need ?



Answer :

To put the unknown in other words, we are to determine a fraction that has a denominator of 10 which should be equivalent to 3/5. If we let x be the numerator of the second fraction such that we form a proportion out of the two fractions that is,
     3/5 = x/10
 The value of x is calculated as below,
          x = (3)(10) / 5 = 6
 ANSWER: 6
