tanner has 36 polished rocks. he put 1/4 of them in a jar for a science experiment. he plans to give 4/9 of them to a friend. how many will he have left?

Answer 1

2/3 multiply 16= 32/3
5/8 multiply 20= 100/8 = 25/2
4/5 multiply 10= 40/5 = 8
7/8 multiply 32= 224/8 = 28
4/9 multiply 18= 72/9 = 8
2/5 multiply 40= 80/5 = 16
3/4 multiply 24= 72/4 = 18
3/5 multiply 15= 45/5 = 9
6/7 multiply 42= 252/7 = 36
1/7 multiply 21= 21/7 = 3
5/12 multiply 60= 300/12 = 25
2/9 multiply 64= 128/9
6/15 multiply 30= 180/15 = 12
3/17 multiply 59= 177/17
11/18 multiply 64= 704/18 = 352/9

20*2/5 = 40/5 = 8 rabbits
20*1/2 = 20/2 = 10 fish
20*1/10 = 20/10 = 2 dogs

40 * 1/4 = 40/4 = $10 to savings
40 - 10 = $30 left
30 * 1/2 = 30/2 = $15 donation

36 * 1/4 = 36/4 = 9 in jar
36 * 4/9 = 144/9 = 16 to friend
36 - 16 - 9 = 11 left

Answer 2

they gave you the answers ill show you how

for the first part

example 1
if your multiplying fractions by a whole number (like 5) put the whole number over 1 (like 5/1). Then you just multiply the top and then the bottom. 2/3 X16/1=32/3=10 2/3

long problem 1
rabits: 2/5=8/20 so 8 rabits
fish: 1/2=10/20 so 10 fish
dogs: 1/10=2/20 so 2 dogs

long problem 2
save: 1/4=10/40 so 10 saved
donate: 1/2=15/30 sp 15 donated

long problem 3
jar: 1/4=9/36 so 9 jarred
friend: 4/9=16/36 so 16 to friend
16+9=25
36-25=11
11 LEFT

Answer 3

2/3*16=32/3=10 2/3
5/8*20=25/2=12 1/2
4/5*10=8
7/8*32=28
4/9*18=8
2/5*40=16
3/4*24=18
3/5*15=9
6/7*42=36
1/7*21=3
5/12*60=25
2/9*64=128/9=14 2/9
6/15*30=12
3/17*59=177/17=10 7/17
11/18*64=352/9=39 1/64
[Please read multiplied by for the sign*]
No of rabbits=20*2/5=8
no of fish=20*1/2=10,and
no.of dogs=20*1/10=2

out of her earnings Melaine saved 1/4
Therefore she saved $40*1/4=$10
Remaining amount=$40-$10=$30
She donates 1/2 of this amount
Hence amount of donation=$30*1/2=$15

Tanner has kept 1/4 of the rocks in thejar
So no of stones in jar=36*1/4=9
No. of stones given to friend=36*4/9=16
Thus he will have 36-25 or 11 stones left

15.11/18*64=33
16.2/5*20=8 1/2*20=10 1/10*20=2
8 rabbits, 10 fish, and 2 dogs
17.$40.00*3/4=$30.00
1/2*$30=$15
She will donate $15
18.1/4*36=9
4/9*36=16
He will have 11 left.

She will donate $15
18.1/4*36=9
4/9*36=16
He will have 11 left.

Answer 6

properly, considering there is plenty right here, enable's do the addition components in a various way. Get stable at it and you may even do those on your head! a million. common rule: while including blended numbers like those upload the entire variety components, then the fractions and combine. So 2 a million/5 + 3 a million/5 = 5 + (a million/5 + a million/5) = 5 2/5. 2. 3 5/8 + a million 4/7. returned we've (3+a million) + (5/8 + 4/7) finished variety section = 4 Now upload 5/8 + 4/7 this is a rule that a/b + c/d = (advert + bc)/bd yet this provides the thank you to function to fractions with diverse denominators: We call it "down product"(advert) + "up product"(bc) divided by skill of "backside product"(bd). So 5/8 + 4/7 = (5*7+8*4)/fifty six = sixty seven/fifty six ultimately we get 4 sixty seven/fifty six or, considering sixty seven/fifty six = a million 11/fifty six, 5 11/fifty six. attempt no.7 this way: 4 2/3 + a million 4/5 finished variety section = 5 2/3 + 4/5 = 22/15 = a million 7/15. answer: 6 7/15. Am I smarter than a 5th grader? purely time will tell! LOL

Answer 7

translation tip
A multiply B = A * B

fraction mulitplication
A/B * C/D = (A*C) /(B*D)
