1) What is 1 2/3 of 1 1/4?
solution:
2) What is N equal to if N x 3/8 = 5/3?
solution:
3) How many 1/8 are there in 2 3/4?
solution:
4) A bag of peanuts has a mass of 2 ½ kg. The mass of cashew nuts is 2/5 that of the peanuts. The nuts are mixed together and packed into 8 packets. What is the mass of each packet?
hey, it's due today and my teacher, I can't really ask her to help me out. maybe someone could at least? pretty please.
+1223 1) \(1 \frac{2}{3} \cdot 1 \frac{1}{4} = \frac{5}{3} \cdot \frac{5}{4} = \boxed{\frac{25}{12} = 2 \frac{1}{12}}\)
2) \(N \cdot \frac{3}{8} = \frac{5}{3}\)
To isolate N, multiply both sides by the reciprical of 3/8, which is 8/3.
\(N = \frac{5}{3} \cdot \frac{8}{3} = \boxed{\frac{40}{9}}\)
3) \(2 \frac{3}{4} \div \frac{1}{8} = 2 \frac{3}{4} \cdot 8 = \frac{11}{4} \cdot 8 = \boxed{22}\)
4) \(\text{cashew nuts mass}= \frac{2}{5} \cdot 2 \frac{1}{2} = \frac{2}{5} \cdot \frac{5}{2} = 1\)
\(\text{total mass} = 2 \frac{1}{2} + 1 = 3 \frac{1}{2} = \frac{7}{2}\)
\(\text{mass per packet} = \frac{7/2}{8} = \boxed{\frac{7}{16}}\)
