One half the number of quarters Diane has
aev [14]
If you want to find half of how many of something divide that number by two. For example if Diane has 8 quarters that you would say 8÷2= 4. So half of the number of quarters Diane has would be 4. Here is another way to do it: You could also multiply 8 by 1/2. And 8•1/2 would be 4. I hope this helps!

Devante buys 1/1/4 pounds of cashews 7 ounces of almonds and 3/4 pounds of pecans how much do the nuts weight in
liberstina [14]

Answer: 39\ \text{Ounces}

Step-by-step explanation:

Given

The amount of cashews is 1\frac{1}{4}\ \text{Pounds}

Amount of almonds 7\ \text{ounces}

The amount of pecans is \frac{3}{4}\ \text{Pounds}

We know, 1\ \text{Pound}=16\ \text{Ounces}

Converting pounds to ounces and adding them

\Rightarrow 1\dfrac{1}{4}\times 16+7+\dfrac{3}{4}\times 16\\\\\Rightarrow \dfrac{5}{4}\times 16+7+3\times 4\\\\\Rightarrow 20+7+12=39\ \text{ounces}\ or\ \dfrac{39}{16}\ \text{Pounds}

Thus, the nuts weigh 39\ \text{Ounces}
