Let Ted be x.
Ed is 7 years older = x + 7
Ed = (3/4)Ted
(x + 7) = (3/4)x
x + 7 = 3x/4
x - 3x/4 = -7
x/4 = -7
x = -28, Ted = -28 years.
(x + 7) = -28 + 7 = -21, Ed = -21 years
Goodness. We had negative numbers for the ages, well does that make sense? No it doesn't.
Our answer is correct. But the sense in the question is lacking. The question has been wrongly set.
<span>We might assume negative ages to mean before they came into the world, before birth! </span>
No regrouping: 4.34 + 4.35
Regrouping (carrying): 4.93 + 3.76
The answer is 18 cups. 8fl=1cup. 144/8=18cups
<span>1. </span><span>The Given problem is to find
where to place the decimal point to the product shown below.
3.9853 x 8.032856, notice that the given equation are decimal numbers with both
ones place value of the whole number.
Now, given the answer 32013341 without decimal point, let’s find where to put
the decimal point.
=> 3.9853 x 8.032856
=> 32.013341
Thus, the decimal point is now located after the 2nd number. We now have 2 whole numbers with value of
tens.
