Step-by-step explanation:
always try to bring fractions you need to compare to the same denominator (bottom number).
we have 9/10 of the pizza left.
then 4/5 if the pizza are eaten.
how to compare 9/10 with 4/5 ?
by bringing 4/5 also to a fraction of 10ths.
what do I need to multiply 5 with to get 10 ?
right, 2.
since we don't want to change the overall value of the original fraction, we need to multiply both levels (numerator and denominator) by that same factor :
4/5 × 2/2 = 8/10
aha !
that we can compare with 9/10.
so, when Lucas ate 4/5 (= 8/10) of the pizza, when there was originally 9/10 left, then we have 1/10 of the pizza left.
They do not appear to be symmectric. they seem to line up well
1). 16 Y= 164. ( then divided)
Y= 164 : 16
Y= 41 : 4
Y = 10 +1/4
2) 8z = 64. (then divided)
z= 64 :8
z= 8
3. D = A•B•C. ( divided)
D : A•B = C
C= D:AB
c. c= d divided by ab
Answer:
<h2>Ceramic does not foster bacterial growth</h2>
Step-by-step explanation:
A good way to think and reason deeply about this is, most if not all toilet bowls are made of ceramics, this is so because ceramics when it dries out kills all hanging bacterial on its surface, hence does not easily permit the growth of bacteria on its surface.
Another wonderful application of ceramic is in the application of water treatment process, specifically in the use as a water filter to kill bacterial, hence it is evident that ceramic does not permit the growth of bacteria
