0.27 ÷ 0.03 = explain each and every step in this process
GREYUIT [131]
0.27 divided by 0.03 = 9


think of it this way it's like doing it 27 divided by 3 which is = 9


but then u see
9x3=27
9x0.3=2.7

so that must mean
9x0.03=0.27
u basically move the decimal point, in this problem its moved 2 or 3 times.

. In a nature conservatory, the ratio of butterflies to total number of flying insects is 36 to 100.
sashaice [31]
Well we already know that the 36:100 is correct because it is the starting amount, to check the 18:50 50 is half of the 100 insects so you would divide 36 by 2 which gives you half of 36 which is 18 so we can check off 18:50 as correct. Idk about the final one but the other two are correct.

Using the 0,1,6,8, and 9, write down all the possible three-digit numbers that have rotational symmetry. the digits can be used
Hunter-Best [27]

Assuming 1 is written rotationally symmetrical, using 0,1,6,8,9 to make numbers that have a degree of symmetry of 2 (i.e. 180 degrees), we can say

one digit numbers: 0,1,8


two digit numbers: 11, 69, 96

(18 becomes 81, so not admissible, similarly for 19, 91,16,61, etc)

(00 is not considered generally as a two-digit number)


three digit numbers:

(000, 010, 080 are not considered generally as a three-digit number)

101, 609, 808, 906,

replace the middle digit successively by 1 and 8 gives

111, 619, 818, 916,

181, 689, 888, 986

for a total of 12 numbers
