Review of Fractions. Lowest Terms Written Exercises A fraction is reduced to lowest terms by dividing both terms by their G. C. D. When, however, a factor common to the numerator and the denominator is apparent, both terms are divided by a common factor until the terms are seen to be prime to each other. 1. Express in its lowest terms. 3. Reduce to its lowest terms. As 299 is not an even number, it is not divisible by 2; the sum of its digits being 20, it is not divisible by 3; not ending in 5, it is not divisible by 5; etc. In this case the G. C. D. is found by continued division to be 23. Note.--A number is divisible by 3 when the sum of its digits is divisible by 3. 4. Reduce to its lowest terms: In this case both terms are divisible by 5, which reduces the fraction to fV. To ascertain if 95 and 171 have a common divisor, test by the method of continued division. (See p. 134.) 5. Reduce to lowest terms: b. 2 6 1 Adding Mixed Numbers Written Exercises 1. How many square feet are there in five steel plates containing, respectively, 12£ sq. ft., 48 J sq. ft., 9 sq. ft., 70$ sq. ft., and 3Jg sq. ft.?
