There are essentially just two ways to write 1/2 as a sum of two basic fractions, and just two to write 1/3 this way.
a) How many ways to so write 1/5 and 1/7?
b) How many ways to so write 1/4 and 1/6?

Wayne, can you see the flaw in my reasoning. I agree with the first 4 being F(2n), but n=5?
1x1x1x1x1 one way; 1x1x1x2 four ways; 1x1x3 x3; 1x4 x2;
2x2x1 x3; 2x3 x2; 4x1 x2; 5
1+8+9+8+12+12+8+5 = 63
Shades of @dmarain , I found myself on New Year's Day, observing the intersecting shadow lunes that form on my Metamucil bottle by the various overhead pot lights.

Longer lives lead to breakthroughs in healthcare and well-being. Longer lifespans foster connections between generations. We need to celebrate longer lives and ensure access to quality healthcare, education, and opportunities for all, regardless of age. #StopAgeism

For subtraction, I really like shifting equally. Here I'd do two moves to make it simpler. 7 less and 500 more:
6015 – 3507 = 6008 – 3500 = 6508 – 4000 = 2508

8% = 8/100 = 4/50
4/50 x 9/9 = 36/450 so
36 is 8% of 450

#MathStratChat I guess I see the proportion built:
32/100 = 16/x. This means 'x' must be half of 100 since 16 is half of 32.

18 is 24% of what? Setting up the proportion: 24/100 = 18/w
24/100 ÷ 4/4 = 6/25
so 6/25 x 3/3 = 18/75
thus 18 is 24% of 75
#MathStratChat partial factoring: 3 x 25 x 4 x 6 = 3 x 100 x 6 or 3x6 x 100 = 1800
3/4 of 24 = 3 x 6 dollars = 1800 cents
Ok actually this is the #MathStratChat for this week. Sorry!

#MathStratChat 6 ÷ 3 = 2. Since we are starting with 3/4 less than 6, we will have an answer that is 3/4 ÷ 3 less than 2. And 2 – 1/4 = 1 3/4

To be different or to introduce another medium, let's think sandwiches. A 12 inch sandwich is a footlong. A third of it is 4 inches and 2/3rds is then 8 inches.
So 11 inches – 8 inches is 3 inches or 3/12 of a foot.
Is there a name for a 1/4 sandwich?

I think decimals jump to mind for this as 0.55 - 0.40 = 0.15 or 15/100 or 3/20
as soon as I did this, 11/20 - 8/20 looks easy too.

Still triggering money with the 1/4, converted 7/20 to 35/100 so 25¢+35¢ = 60¢ so 0.60 or 6/10 = 3/5

Americans should be able to trust that our leaders will safeguard the hard-earned Social Security and Medicare benefits they have contributed to and earned throughout their lives. @AARP is encouraged to hear this commitment echoed tonight. #SOTU spr.ly/60103cn0p

At #EDcampBCCC this morning, I was inspired to give thoughts to how the new reporting order, core competencies, self-reflections through the use of metaphor, prompts and templates (with choice & sliding proficiency scales). "Weaving" with friendly language for parents/Ss too.
