25% is a quarter so halve 130 and the halve the answer...
2 + 3 = 5 quarters or 1 1/4 (one and one quarter)
You divide it by 4. So 16 ÷ 4 = 4 Or you can halve it to get 8 and halve it again to get 4
It is reduced by a quarter. If you halve the you also halve the diameter The area (A) of a circle is = pi x (radius)squared. If you halve the radius and then square it then to balance the equation the area must be divided by Four.
y is directly proportional to a, for any value of b (other than 0). If you double a, you double y; if you quadruple a, you quadruple y. Similarly, if you halve/quarter a, then you halve/quarter y.
When you halve a quatity in a division, it's equivalent to doubling the divider. In other words, one half is written as 1/2, and one quarter is 1/4. So half of a quarter cup would be one-eighths of a cup (1/8).
Neither.
either halve the halve to make a quater or just keep on halving it
