Hello GREATMINDS💡 So today on MATHSPEDIA A+🧠we shall discuss and focus on  5  more Arithme-tricks😉 on multiplication of some digits After the lesson if there is a part you don't understand  feel free to comment Fig 1. So let's begin  1. Multipy by 5         -1- 1234×5 = 6170 Step 1- Divide the number by 2 1234 /2 =617 Step 2- Multiply the result from Step 1 by 10 617×10 = 6170 Fig 2. 2. Multiply by 6     -1- 16×6 = 96 6= 5+1= (10/2)+1 Step 1 - Divide the number by 2 16 /2= 8 Step 2 - Multiply the number from Step 1 by 10 8×10 = 80 Step 3- Multiply the number by 1 16×1=16 Step 4- Add Step 2 and 3 80+16 = 96 Fig 3. 3. Multiply by 20 -1- 36×20 = 720 Step 1- Multiply the number by 2 36 × 2= 72 Step 2- Multiply the number from Step 1 by 10 72×10= 720 Fig 4. 4. Multiply by 25 -1- 18×25=450 Step 1- Divide the number by 4 18/4 = 4.5 Step 2- Multiply the number from Step 1 by 100 4.5×100 = 450 Fig 5. 5. Multiply by 50 -1- 18×50 =900 Step 1- Divide the number by 2 18/2= 9 Step 2- Mult

Hello GREATMINDS💡 So today on MATHSPEDIA A+🧠we shall discuss and focus on  5  more Arithme-tricks😉 on finding percentage % After the lesson if there is a part you don't understand  feel free to comment Fig 1. We all probably know that when we hear percentage we think of 100. So here are 5 amazing tricks that can help to find percentage of some numbers without the use of a calculator. So let's begin We'll start with some tips 1. Tip -1- 15% of 300 =45 Step 1- Calculate 10% 300/10 = 30 Step 2- Calculate 5% of the answer from Step 1. 5% of 30= 15 Step 3- Add step 1 and 2 30+15= 45 Fig 2. 2. 5% of numbers -1- 5% of 60= 3 Step 1- Divide the number by 10 60/10 = 6 Step 2- Divide the number from Step 1 by 2 6/2 = 3 Fig 3. 3. 20% of numbers   -1- 20% of 255= 51 Step 1- 20% = (100/5)% Step 2- 255/5 = 51 Step 3- 5=10/2 Step 4- Divide the number by 10 255/10 = 25.5 Step 5- Multiply the number from Step 4 by 2 25.5 × 2=51 -2- 20% of 255 = 51 Step 1- Divide the number by 10 255/10
