AREA AND PERIMETER UNIT TEST.
ETHAN WRITES THE RATIO X/8= Y/16 TO HELP HIM REDUCE THE SIZE OF A TWO-DIMESIONAL SHAPE. IF THE NEW VALUE OF Y IS 3 UNITS, WHAT WILL BE THE VALUE OF X?
1. 1.5 UNITS
2. 3/16 UNITES
3. 6 UNITS
4. 0.5 UNITS
To find the value of X, we can use the ratio X/8 = Y/16 and plug in the new value of Y which is 3 units.
X/8 = 3/16
Cross multiply:
16X = 24
Divide by 16:
X = 24/16
X = 1.5 units
So the value of X is 1.5 units.
Therefore, the correct answer is:
1. 1.5 units
