Mathematics
1 answer:
slavikrds [6]3 years ago

Answer: -\frac{5}{12}

Steps:

1\frac{1}{4}\times \left(-1\right)\frac{1}{3}

Convert mixed numbers to improper fractions: 1\frac{1}{4}=\frac{5}{4}

=\frac{5}{4}\times \left(-1\right)\frac{1}{3}

\mathrm{Apply\:the\:rule}:\quad \:a\left(-b\right)=-ab

\frac{5}{4}\left(-1\right)=-\frac{5}{4}\times \:1

=-\frac{5}{4}\times \:1\times \frac{1}{3}

\mathrm{Apply\:rule}\:a\times 1=a

=-\frac{5}{4}\times \frac{1}{3}

\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}

\frac{5}{4}\times \frac{1}{3}=\frac{5\times \:1}{4\times \:3}

=-\frac{5\times \:1}{4\times \:3}

\mathrm{Multiply\:the\:numbers:}\:5\times \:1=5

=-\frac{5}{4\times \:3}

\mathrm{Multiply\:the\:numbers:}\:4\times \:3=12

=-\frac{5}{12}

Dmitriy789 [7]

Answer: 600 canned foods was the total.

Step-by-step explanation: We need to find out what‘s 100% of 480. Since 480 canned foods is 80%, we can divide 480 by 8 which gives us 60. Aka 60 canned foods = 10%. Now, we multiply 60 by 10 which gives us 600. Hope this helps!

Melissa is stacking storage cubes in a crate the bottom of the crate is 8 inches by 12 inches. The volume of the crate is 768 cu
Karo-lina-s [1.5K]

Answer:

12 cubes can fit in the create.

Step-by-step explanation:

We know that the volume of a the crate is 768 in³, and the definition of the volume is:

V=A*h

Where:

  • V is the volume
  • A is the area (A=8*12 in²)
  • h is the height

So h=\frac{V}{A}=\frac{768}{12*8}=8 in    

Now, we know that the storage cube has a length of 4 in so we have a volume equal to 64 in³. Therefore we just need to divide 768 in³ by 64 in³ it is 12.

Finally, 12 cubes can fit in the create.

I hope it helps you!
