Han found a way to compute complicated expressions more easily. Since 2 ⋅ 5 = 10, he looks for pairings of 2s and 5s that he knows equal 10. For example, 3 ⋅ 24 ⋅ 55 = 3 ⋅ 24 ⋅ 54 ⋅ 5 = (3 ⋅ 5) ⋅ (2 ⋅ 5)4 = 15 ⋅ 104 = 150,000. PLEASE HELP ME

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
