Yesterday she walked 7/3 miles and today 7/3 x(1 + 3/4) which should be added, i.e. 7/3x(2 + 3/4) ...
Left of x sign we have a fraction whose numerator is 10 times its denominator because the same number is divided by 10 in the numerator and by 100 in the
denominator .
Today he did 1/3 + 1/3 x 1/4 = 1/3 x (5/4)i.e. 5/12 of the work in 3 hours. That means he does 1/12 of it in 3/5 hours.
Yesterday he did 1/3 of the work and there remained 2/3 of it. Let the amount of work remainig from yesterday be A. If he does 4/7 of A today, he will have
done 1/3 more than 3/7 which he will do tomorrow. So to complete A he needs normally 7 hours .
The parts will be 3/9, 2/9 and 4/9 .
Please have a look at ry1.
He drove 225 km. till he stopped. 225 + 45 makes 270 which is 3/5 of his destination .
1/5 x 2/3 x 33/15 and 3 and 33 are to be ... ?
2/3 L = 28/3 feet .
They are the first 3 elements of the series 1/n and 1/n^{2} and important.
In this case do the summations first. They are 11/6 and 49/36 .
10/39 x 117/1000 = 3/100 . 36x3 = 108
The three possible ways and their probabilities for one of the particles are in ry1.
The total probability is for one particle case is 2/125 + 4/125 + 4/125 . Symmetry requires twice an amount .
Just set A=1 and B=2. You now have 1212/120 x 2121/210. Write it in the form (1200/120 + 12/120) x (2100/210 + 21/210) = 101/10 x ... .
From each lb. of smarties he obtains 33 packs. 2/3 x 33 = 22 . A total of 253 packs whose 8/11 is sold. 8x23 = 184 .
$25/9 for bag material and $12/5 for pocket material.
He will need 3/144 cup for each ginger snap and 1/192 cup for each piece of sandies .
M-36 = G means M+8-44 = G and with (M+8)/3 = G+8 it means G+44 = 3xG + 24. So 2xG = 20 .
Take care that is average speed is known. Look for further help in ry1.
23/100 x 3 600 000 000 000 = ?
7/25 x 1/5 = ?
Receipts share is 23/36 . This means, without making any detailed calculations , ...
For the interval 1987-2012 it may be plausible to say defence spendings have decreased by 1/4 . Look at ry1.
Reduced by 1/4 from 29.7 % it will be 22.275 % and reduced again by 21/200 it will be, as a mixed number, 19 83/100 %.
a is smaller than d and c . a is 5/110 b is 6/165.
First reduce the fractions: 7x8 + 43/5 x 9x9. Then multiplications: 56 + 3483/5 = 56 + 3480/5 + 3/5 = 702 ...
3 1/6 - 2 1/6 = 1
