Answer:
7y4
Step-by-step explanation:
7 is the highest number that can go into all three numbers
The digits on the right side are half the value on the left ones
0.25 kilometers
Using the universal measurement
Kilo, hecto, deca, unit, deci, centi, milli
Kilometer, hectometer, decameter, meter, decimeter, centimeter, millimeter
From unit you would move three time to the left from your decimal point on your starting number 250. You would move it three times to the left because meter to kilometer is three decimals to the left
A way I remember my universal measurements is king (k-kilo), Henry (h-hecto), died (d-deca), unexpectedly (u-unit as in liters, meters, grams) drinking (d-deci), chocolate (c-centi) milk (m-milli)
You do 28/100 which is 0.28
You then multiply this by 21
28/100 x 21 = 5.88
