minus-squareplague-sapienslinkfedilink12•edit-28 months agoIts easier: 10% of a 100: 100 * 0,1 = 10 2,5% of 33: 33 * 0,025 = 30 * 0,025 + 3 * 0,025 = 0,75 + 0,075 = 0,825 Thats how I calculate it mostly in my brain. But being smart I usually just type everything (like 9*9) in the calculator xD
x% × y = x × y ÷ 100 This helps you out much more.
Its easier:
10% of a 100: 100 * 0,1 = 10
2,5% of 33: 33 * 0,025 = 30 * 0,025 + 3 * 0,025 = 0,75 + 0,075 = 0,825
