3/4 × 2/5 = (3×2)/(4×5) = 6/20 = 3/10
1/5
3/5 * 1/4 = 3/20
1 and 1/3 = 4/3 1 and 1/4 = 5/4 4/3 x 5/4 = 20/12 = 5/3 or 1 and 2/3
2/5 multiply times 2(because .1=1/10). that equals 4/10 in decimal form that is .4(again, because .1=1/10).
2/5
Well 4 times 2 should be fairly straight forward (4*2=8) 2 over 5 means that 5 should be multiplicated by it self 2 times (5*5=25)
1/2
2 4/5
(2/3) * (4/5) = 8/15
5/3 x 4/5 x 3/2 = 60/30 = 2
(4/5 )x 2=8/5=1.6
It is: 5/9 times 4 = 2 and 2/9 as a mixed number
4 and 5 are both times by 2
(3/4)(16/21)(7/10)=(2/5) or 2 over 5, or 2 fifths.
4
2*3=6 5*4=20 answer is 6/20
