УелЯдб 137 - Cubic Measure 1728 cubic inches (cu. in.) =1 cubic foot (cu. ft.) 27 cubic feet = 1 cubic yard (cu. yd.) 128 cubic feet = 1 cord (cd...
УелЯдб 110 - Reduce the fractions to a common denominator and divide the numerator of the dividend by the numerator of the divisor.
УелЯдб 134 - SQUARE MEASURE 144 square inches (sq. in.) = 1 square foot (sq. ft.) 9 square feet = 1 square yard (sq.
УелЯдб 86 - Multiplying or dividing both terms of a fraction by the same number does not change the value of the fraction.
УелЯдб 75 - Cancel the common factors from both the dividend and divisor. II. Then divide the product of the remaining factors of the dividend by the product of the remaining factors of the divisor, and the result will be the quotient.
УелЯдб 101 - Multiply the whole number by the numerator of the fraction, and divide the product by the denominator ; or divide the whole number by the denominator of the fraction, and multiply the quotient by the numerator.
УелЯдб 70 - Divide the given number by any prime number greater than 1, that will divide it without a remainder, and the quotient, if composite, in the same manner; and thus continue until the quotient is prime. The divisors and the last quotient will be the prime factors required.
УелЯдб 150 - Number. 12 units — 1 dozen (doz.). 12 dozen = 1 gross (gro.). 12 gross =• 1 great gross. 20 units — 1 score.
