We'll be glad to check your answer.
150/100 = 1.5
just follow the recipe
9 more probloms on this lesson
Ms. Sue - we have been at this for quite a while, just working it out :)
i see the recipe now
i did 5/6 +3/6 and got 8/6 i reduced and got 4/3 what do i do?
is that right 4/3?
yes, good
ok just cheking
on that one
by the way 4/3 is 1 1/3
solve the equation by undoing
x-3.5=18.7
I do not know what undoing means
but try adding 3.5 to both sides
yes u do the oppsitsit
is it 29.2?
18.7 + 3.5 = 22.2 you have a typo
ware
i am dad in english
sorry bad
x-3.5=18.7
x - 3.5 + 3.5 = 18.7 + 3.5
x + 0 = 22.2
ok i see
52x=676. i first do 676/52 right?
yes, divide both sides by 52
is it 13?
52 x / 52 = 676 / 52
or
x = 676 / 52
which is 13
:)
it comes to 13
ok x/21=0.5
multiply both sides by 21
ok i 0.5*21=10.5 right?
yes
x+2/3=4/3 i divided 2/3 /4/3 right?
NO SUBTRACT 2/3
x + 2/3 - 2/3 = 4/3 - 2/3
which is 2/3
0.6666666
6/5x=1/10
i divid right?
well, same as multiply by 5/6
(5/6) (6/5) x = (5/6)(1/10)
1 x = 5/60
but
5/60 = 1/12
check :
(6/5) (1/12) = 6/60 = 1/10 check :)
so it is 1/12?
i see it now
2 more now
sorry 3
good
dividing by 6/5 is multiplying by 5/6
no 2
LOL getting tired ?
x/4/3=7/8
me no
jazzy is tired
I think that means
x / (4/3) = 7/8
multiply both sides by (4/3)
OK!!!!!!!!!!!!!!!!1
is 1/8 = to 125%?
(4/3) [ x / (4/3) ] = (7/8 )(4/3)
x = (7/2)(1/3)
x = 7/6
or
1 1/6
==========================
check
(7/6)/(4/3)
= (7/6)(3/4) = 21/24 = 7/8 right check
ok it is 1 1/6
1/8 = 0.125
=times 100
= 12.5 %
be more careful
i thot it was 0.125=1/8
1/8 is smaller than 1
125% is bigger than 1
no way the same :)
percent to decimal divide by 100
decimal to percent, multiply by 100
100/8 = 12.5
yes .125 = 1/8
but .125 * 100 = 12.5 %
not 125 %
last one 4/7-1/2=
ok i see.
factor 7 = 1 and 7
factor 2 = 1 and 2
so
LCD = 2*7 = 14
4/7 = 8/14
1/2 = 7/14
----------- subtract
answer 1/14
