Another way to express 52+24
Furkat [3]
We know that:  52 + 24 = 76.
You can also express it this way:
52 + 24 = 50 + 2 + 20 + 4 = ( 50 + 20 ) + ( 2 + 4 ) = 70 + 6 = 76
Or ( since 4 * 13 = 52 and 4 * 6 = 24 ):
52 + 24 = 4 * 13 + 4 * 6 = 4 * ( 13 + 6 ) = 4 * 19 = 76.

Mary is making some shirts for her school's drama department. The fabric store has 3 1/6 yards of the fabric she wants in stock.
ddd [48]
The answer is <span>4 3/4 yards of the fabric.</span>

This can be calculated using the proportion.
If the 3 1/6 yards of the fabric is enough for <span>1 1/3 shirts, how many yards are necessary of 2 shirts:
</span>3 \frac{1}{6} yards :1 \frac{1}{3}shirts =xyards:2shirts

Let's express 3 1/6 as 19/6:
3 \frac{1}{6} =3+ \frac{1}{6} = 3* \frac{6}{6}+ \frac{1}{6} = \frac{18}{6} + \frac{1}{6} = \frac{18+1}{6} = \frac{19}{6}

Similarly, 1 1/3 = 4/3:
1 \frac{1}{3} =1+ \frac{1}{3} = 1* \frac{3}{3}+ \frac{1}{3} = \frac{3}{3} + \frac{1}{3} = \frac{3+1}{3} = \frac{4}{3}

Now, let's use this in the proportion:
<span>3 \frac{1}{6} yards :1 \frac{1}{3}shirts =xyards:2shirts
</span>\frac{19}{6} : \frac{4}{3} = x:2

Crossing the products:
x* \frac{4}{3} =2* \frac{19}{6}
⇒ x* \frac{4}{3} = \frac{19}{3}
⇒ x = \frac{19}{3} : \frac{4}{3}
x= \frac{19}{3} * \frac{3}{4}
⇒ x = \frac{19}{4} = \frac{16+3}{4} = \frac{16}{4} + \frac{3}{4} =4+ \frac{3}{4} =4 \frac{3}{4}

Therefore, Mary needs in total 4 3/4 yards of the fabric.
