Answer» ber of bags has to be a divisor of 70 already 240 and it has to be maximum. Therefore, your gcd. We decompose the numbers: 70 = two ⋅ 5 ⋅ 7 240 = two 4 ⋅ 3 ⋅ 5 The common bases are two Y 5 and its minor exponents are 1 Y 1 . Therefore, m C d ( 70 , 240 ) = two 1 ⋅ 5 1 = 10 MUST buy 10 sacks. Each bag will have 7 KG of cement and 24 of sand. |
