Answer:
222
Step-by-step explanation:
42/3 x 111/4 = (42 x 111)/(3 x 4)
42/3 x 111/4 = 2664/12
42/3 x 111/4 = 222
<span>584 1/4 minus 18 3/4 equals 565 1/2</span>
So the first one, 1.2 >11/5. and the second one 1/3> 1/2
1,300 students will be left
10a + 8b = 230
a + b = (2 + 2 + 13 + 10)...a + b = 27 (this is the number of gifts to buy)
a = 27 - b
10(27 - b) + 8b = 230
270 - 10b + 8b = 230
-10b + 8b = 230 - 270
-2b = -40
b = -40/-2
b = 20 <=== she bought 20 eight dollar gifts
a = 27 - b
a = 27 - 20
a = 7 <=== she bought 7 ten dollar gifts
